Specification of Letters Patent.

Application filed March 5, 1913; Serial No.'7 52,096.

, exact description thereof.

Theobject of my invention has been to provide a jacket for use in molding, which, shall have among others, any or all of thefollowing advantages: that it shall be capable of being put upon or about a sand mold in such a way that its parts shall accurately and eifectively fit and sustain the sides of said mold; that its'parts or sides shall be flexibly or j ointedly connected so as to adapt themselves to the sides of the mold however irregular, and that: itshall be cheap, durable and practical in construction. And-to such ends my invention consists in the jacket for use in molding hereinafter specified.

In the accompanying drawings Figures 1,

2 and 3 are respectively, a bottom plan view, I

a side elevation and an end elevation of a acketembodying my lnvention. F1 gs. 4 and 5 are enlarged plan vlews of dlfl erentforms of connection between the sides of my jacket.

Fig. 6 is a side elevation of Fig. 5. 4

My invention is capable of embodiment in many difierent forms and the illustrated embodiment is therefore to be regarded as typical only of many possible embodiments.

Jackets embodying my invention are capabio of use in a variety of ways, and while I shall illustrate the use of one embodiment of my inventionby a specific example, such example is to be regarded as typical only.

As an example of foundry practice involving the use of a form ofmy acket it may be assumed that a-mcld has been made of. sand or other suitable material consisting of, an"

upper part, orcope and a, lower part, or drag, containingffwithm and between them the cavity of the shape of the article to be 1 cast. After the mold has been formed, it it is properly formed, it does not need any&

thing to sustain it except at the time, when the metal is poured into the mold anduntil the metal or other substun'ceto be cas t has; set or begun to set. It-IS, howevencustom- My to remove th fiask from the mold. so

the metal, removing it as ,soonas the metal. has set and using the jacket for casting in other molds. My jacket is especially intended for such use asithat of the jacket.

My jacket in the form illustrated in Figs. 1, 2 and 3 consists of long sides 1 and short sides 2, which are so connected thatIt-hey can have movement relativeto each. other, and preferably universalhmovementh In this form of my invention the connection consists of straps 8, which in the resent instance are illustrated as formed 0 leather or asbestos and are secured to the sides as by bolts 4. The sidesare preferably trapezoidal in formand the straps are preferably so connected to thenrthatmyjacket will nor mally have the formof a truncated pyramid, so as to adapt it foruse on' a tapering mold. These sides may, however, consist of parallelograms for use with a mold whose sales are vertical. v I

Assuming the mold to be in the form of the frustum of apyramid', my jacket is simply pressed downwardalong the sides of the mold until all of thesides of the jacket bear firmly against the sides of the mold. Because of the flexible connection between the sides, a single'lone of my jackets can fit molds of a wide variety-of dimensions, proportions and defects.

If the mold onlyvaries fromthe normal shape of my jacket by any reasonable amount the variable connections will permit" the necessaryaccommodation, If, however, the mold be substantially shorter than the jacket, it is'only necessary topress one of the end plates of my jacketdownward below the level of tl esidemwvhen the diagonal position of the connecting straps will in effect cause the shorteningof thev jacket. In the same manner anadjustment canbe made 'for the unusual difference, in. width. of the jacket. r g

' In the form of,jmyyinvention shown in Fig. 4 the connection consists of plates 5 secured tOtllQ'flflSltSldS 6 and having ears .7 standing in substantially.- parallel .rela tion. The bolt- 8ipasses loosely through the said. ears so as to permit; greatfreedom I of .motion of, the-bolt relative to .the ears: I preferably.v rovidefi'a ;coil.,spr131g,9 stir-- rounding the oh; and bearingbetween the I Fig. 5, I'make the connection in the form I thereof.

of a double hinge, the connection, as shown, consisting of plates 10 secured to the sides 11 and carrying pairs of parallel ears 12 which support pins 13. The link 14 lies between the ears of each pair and connects the pins 13, the link having holes larger than the pins and being thinner than the space between the ears so as to permit great freedom of motion.

It will be observed that my molding jacket is capable of fitting molds of Widely different variety, whether having vertical or tapering sides, whether the sides are parallel or not, whether the sides are of equal dimensions (within considerable limits), or whether ornot there be other defects present. It will also be observed that my jacket is simple and cheap in construction and is durable.

I claim:

1. In a molding jacket or casing the combination of sides, and connections between the ends of adjacent sides permitting relative movement in more than one plane, every side of the jacket being movable relative to each of its neighbors.

2. In a molding jacket or casing the combination of sides, and connections between the ends of adjacent sides permitting rela: tive movement about more than one axis, every side of the jacket being movable relative to each of its neighbors.

3. A molding jacket consisting of a plurality of sides and a universal connection between each two sides.

'45. A molding jacket consisting of a plurality of sides and a flexible connection between the adjacent ends of each pair of sides. I

5. A molding jacket consisting of a plurality of sides and a connection between the ends of said sides permitting relative vertical, adjustment thereof.

6. Amolding jacket consisting of a plurality of sides and a connection between theends of each two adjacent sides permitting relative horizontal adjustment 7. A molding jacket consisting of a plurality of sides and a'connection between the ends of each two adjacent sides permitting relative bodily displacement.

8. A molding jacket consisting of a plurality of sides and a connection between the ends of said sides permitting relative movement to different levels.

9. A molding jacket consisting of the combination of sides and means universally connecting adjacent ends of each pair of sides.

10. A molding jacket consisting of the combination of sides, and a connection between the adjacent ends of each pair of sides, said connection being capable of moveof the sides whichi ment relative to each permit variations of size or 13. A molding jacket consisting of the combination of sides, and a connection between the adjacent ends of each pair of sides, said connection having a substantially universal connection with each end of a side with which it is connected, said sides being spaced apart when said connection is at normal length.

14. A molding jacket consisting of aplurality of sides and a universal connection between two adjacent sides at one or more corners.

15. A molding jacket consisting of a plurality of sides and a flexible connection be tween two adjacent sides atone or more corners.

16. In a molding jacket or casing'the combination of sides and a connection between-two adjacent sides at one or more corners, permitting. relative movement in more than one plane. I

17. A molding jacket consisting of four connected sides and provided with means permitting two opposite sides to recede from each other and at the the other two opposite sides to approach each other.

18. A molding jacket for supporting the sides ofa sand has been removed, comprising a plura ity of sides and means for connecting two or more sides together to permit, without adjustment, either the alteration of the relative inclination of the sides, the size, or shape, or both size and shape of the space inclosed by said sides, whereby the jacket will be automatically accommodated to variations of the sand mold.

19. A molding jacket for supporting the sides of a sand mold after the molding flask has been removed, comprising a plurality of sides and connections between two adjacent sides at two or more corners to permit, without adjustment, either the, alteration of the relative inclination of the sides, the size, or the shape, or both size and shape of .the space inclosed by said sides, whereby the jacket will be automatically accommodated to variations of the sand mold.

20. A-molding jacket consisting of a plurality of sides and a doublev hinge connecsame time causing mold after the moldin flask tion between two adjacent sides at one or more corners.
